BACKGROUND AND OBJECTIVE: Pneumonectomy (PNE) is a procedure infrequently performed in children. A high morbidity/mortality rate associated with PNE has been described. Few series have been published in the last 15 years. Risk factors associated with morbidity/mortality after PNE were evaluated. Indications, course, survival and complications of PNE in children were also analized. METHODS: In a case series of 51 children who underwent PNE, death within 30 days of surgery, pneumonia, empyema, sepsis, adult respiratory distress syndrome, bronchopleural fistula, bleeding, pneumothorax and post-PNE syndrome were considered major morbidities. Scoliosis, wound infection and atelectasis were considered minor morbidities. RESULTS: Median age at PNE was 7.4 years; 45% were males. Indications of pneumonectomy were postinfectious bronchiectasis (61%), tumours (17%), pulmonary malformations (17%), aspiration syndrome (14%), cystic fibrosis (6%), immunodeficiency (4%) and trauma (2%). Mortality rate was 4% at 1 month. Major and minor morbidities were present in 23% and 27% of patients, respectively. Risk factors for development of morbidities after PNE were age ≤ 3 years (OR: 16.7; 95% CI: 2.4-117) and the need for mechanical ventilation for at least 4 days (OR: 8; 95% CI: 1.5-43.6). CONCLUSION: Children are at high risk of death, major and minor morbidities following PNE. Caution is recommended for this group of patients.

PURPOSE: Primary lung tumors are rare during childhood and encompass a wide variety of histological types. Each has a different biology and a different therapeutic approach. The aim of this article is to review the experience of a pediatric referral center with this kind of tumors during the last 24 years. METHODS: A retrospective chart review was performed for patients with diagnosis of primary lung tumor between the years 1990-2014. The variables analyzed were age, sex, course of the disease, symptoms, localization, surgery, histology and outcome. RESULTS: Between 1990 and 2014, 38 patients with primary lung tumors were treated at our institution. Age at presentation was 6.6 ± 5.2 years (r 0.91-16.58) and the female:male relationship was 1.37. Inflammatory myofibroblastic lung tumor (n = 13), carcinoid tumor (n = 6) and pleuropulmonary blastoma (n = 6) were the most frequent histological types. Persistent radiographic abnormality was the most frequent presenting sign (34 %). Global mortality was 15.8 % varying according to histology. CONCLUSION: Although the diagnosis of primary lung tumor is rare, the persistence of a radiographic abnormality in spite of adequate treatment for inflammatory processes forces us to evaluate further. The age of the patient is an important factor in the decision of the diagnostic work-up.

PURPOSE: Megaprepuce is a congenital penile malformation that includes phimosis and severe ballooning of the internal prepuce. We combined the main technical details of 2 previously reported surgical techniques to simplify the surgical approach. We report the key points of this revisited surgical correction for megaprepuce and the long-term results. MATERIALS AND METHODS: Penile reconstruction was performed between March 2004 and March 2009 in 26 children 2 to 19 months old (median age 6) with congenital megaprepuce. Surgical repair consisted of limited preputial resection of the phimotic ring, wide dissection of the outer prepuce to the base of the penis, fixation of the proximal outer prepuce to Buck's fascia to create a new penoscrotal junction, and unfurling and wide tailoring of the inner prepuce in the ventral midline to resurface the whole elongated penile shaft. A bladder catheter was left in place for 5 or 6 days. Only patients with at least 6 months of followup were included in analysis. RESULTS: All patients underwent surgery on an outpatient basis. Operative time was between 50 and 85 minutes. Median followup was 17.6 months (range 6 to 59). Two patients had slight dehiscence of the ventral suture, which healed spontaneously without a scar. In 1 patient transient urethral meatal stenosis developed. The final cosmesis result was adequate in all patients. CONCLUSIONS: It is possible to correct megaprepuce and achieve an adequate genital aspect with a simple approach of resurfacing the penis with the unfurled, tailored inner prepuce.
